Question

na proporção x-2\10 = m\3, se m =1, qual o valor de x

Answer 1

Se for (x-2)/10, x=(10/3)+2, x=16/3
Se for x-(2/10), x= 1/3 + 2/10 = 8/15

Answer 2

$\dfrac{x-2}{10} = \dfrac{m}{3} \\ \\ \dfrac{x-2}{10} = \dfrac{1}{3} \\ \\ 10 \cdot 1 = 3 \cdot (x-2) \\ \\ 10=3x-6 \\ \\ 10+6=3x \\ \\ 16=3x \\ \\ 3x=16 \\ \\ x= \dfrac{16}{3}$
